HEARCAT? Do you have any advice on the congestion in my INNER EAR?

I have been experiencing some problems with my ear, I was a bit dizzy, very nauseas and the hearing in my left ear sounds as though I am under water or as if a robot is speaking. I figured this was all due to an inner ear congestion. I went to the doctor, and was correct. He prescribed me some Phenergan for the nausea, and told me to take motrin 600 mg (which was harsh on my stomach) and to take Zyrtec. My hearing in my ear is really aggrivating, and I can’t stand when anyone talkes because I cannot makeout what is being said in that ear. I just want to know if there is anything else I can do in order to clear the congestion in the Eustatian tube. I just want to hear at leat a bit better…any suggestions?
